Abcam, ab275920-25mg, 2',7'-Dichlorofluorescein di-β-D-galactopyranoside (DCFDG)

Key facts
CAS number:17817-20-8,
Purity:>98%,
Form:SolidSee storage information,
Molecular weight:725.48 g/mol,
Nature:Synthetic,
Solubility:Soluble in DMSO,
Biological description:Highly sensitive fluorescent substrate for measuring galactosidase and galactocerebrosidase activity. Since the pKa of the released fluorophore is significantly lower than comparable fluorophores, it can retain appreciably more fluorescence in the highly acidic environment of the lysosome than other similar fluorophores. Absorption prior to enzyme hydrolysis is 290 nm.,
Excitation/Emission:Ex: 495nm, Em: 529nm
